Question about Toshiba 65H81 65" Rear Projection Television
I have a toshiba 65h81 that the convergence messed up on. I tried using the Touchfocus but got "touchfocus error" We went into the service menu and can't get that red to go any further down. It's only on the bottom left and top right. Took off the screen and it doesn't appear there is any issues with the red gun as we can see it move up and down, etc...
Pretty sure it's the IC chipset based on what most people have said but not exactly sure how easy/difficult of a job it is. From other posts, it looks like chips are between $7-$45.
I can get it fixed for $250...Should I have it fixed at all. Is $250 too much to fix it? If it's easy, how do I do it and does it require any sodering? Is there any other things I should check before going forward?
Also, how many chips would I need, where can I buy them and how difficult is it?
Guys, I 've replaced my STK's and and it was a 2 and a half hour challenge job for me, in the hope I solve the dreaded red light blinking issue. I have soldered both STK's nice and neat and everything looks in order. One of the problems you might face, is your soldering gun. There are 4 heavy duty pins that keeps each STK in place, and you need a powerful gun to take care of those. The rest of the pins are very small, and you need a different setup for your soldering gun. You also need a suction pen to be able to to take all those pins out.
But it's not a heavy headache, it's just a light one:)
Also the thing is to remember each wire assembly you disconnect and put it back. It takes patience, and you don't wanna destroy them :( For some , that by itself could be a challenge. The Board containing the two STK's is connected to the power board with three neat assemblies....you pry those up from the top suction, and away from the power board.
BUT, as I recall, most of the challenge has to clear that board loose.
I hope this helps.
